That would work as well Jan although it sounds as if the structure the OP wants is something similar to this:
-- Site Root
--- First Master
---- First Home Page
So with that being said David, why not create your "Home" pages for the individual sections within the secondary masterpage (First Master) level? This will allow you to get the desired functionality, you just have to remember to check the "Hide on sub pages" check box on the items you don't want in the sub levels.
